Jacob & Co. Japan announced the Epic X GoMining on January 27, 2026, a limited-edition collaboration with Bitcoin-mining infrastructure company GoMining. The watch pairs a 44 mm black DLC-coated stainless-steel case with a hand-wound skeleton movement; Jacob & Co. says production is limited to 100 pieces worldwide. The announcement does not give a price or confirm current stock.
What is the Jacob & Co. Epic X GoMining?
Epic X GoMining is a named collaboration between Jacob & Co. and GoMining. In its announcement, Jacob & Co. Japan presents the watch as a meeting of mechanical-watch construction and Bitcoin’s structure. The X-shaped bridge and skeletonized dial are central to that idea, with Bitcoin-inspired graphics on the bridge. These are the issuer’s descriptions of the design, not claims about the watch’s ability to mine Bitcoin or produce investment returns. Jacob & Co. Japan’s announcement was published January 27, 2026.
The brand describes the Epic X design approach as 「単純な装飾ではなく、構造そのものが造形となり意味を持つ」—translated as “Rather than simple decoration, the structure itself becomes form and carries meaning.”

How it differs from other Epic X watches
Epic X is a family of distinct models, not one fixed specification. Jacob & Co. Japan’s 2025 collection overview lists variants including Epic X Sport, Chrono, Ceramic, Tourbillon Baguette and Twin Dragon. The sources differ on when the collection began: the Japanese overview dates its birth to 2015, while the official Chrono page says it launched in 2016. It is therefore more accurate to describe the collection as introduced in 2015–2016 than to present one date as uncontested. Jacob & Co. Japan’s 2025 overview and the official Epic X Chrono 47MM page provide those accounts.
